This Christmas season, Williams was the recipient of the Battlestar Galactica Blu-ray box set, and he's already on his third trip around that galaxy. He also cites The Expanse's space opera awesomeness as one of his other TV addictions, and geeks out about getting the opportunity to meet up with the cast at last year's San Diego Comic-Con.

Have a listen above to Williams revealing the nerdier corners of his universe, all while sitting next to his Black Lightning co-star, James Remar (The Warriors, 48 Hours), who also happened to guest star on BSG.
